Title: Cop yarn end detaching appts. -  has cuff with jets to loosen yarn end with inner air guides to prevent snagging
Inventor: ENGELHARDT DIETMAR
IPC: B65H67/08
Filed: 1990-09-26
Abstract: The appts. to detach the yarn end from a supply cop, standing vertically at the automatic winder to feed the yarn through for winding, has a cuff round the cop with jets to deliver a spiral air stream between the cop and cuff in the unwinding direction, while the take-off accelerator at the head of the cop is withdrawn into the inoperative position. Passive air guides are at the inner surface of the cuff to prevent the detached yarn from snagging at the inoperative take-off accelerator. Pref. a projection at the inner surface of the cuff, extending inwards, is in front of the inoperative take-off accelerator in the direction of air flow, for the detached yarn and the air carrying it to slide over the projection. The projection extends on the line of the take-off accelerator, towards the longitudinal axis of the cuff, at least over a part of the extended line. The projection has at least one break. The inner surface of the cuff has at least one recess, to accommodate the take-off accelerator. The take-off accelerator has a number of blades which, when closed, form a central yarn guide opening for the bobbin supply operation and, when opened, do not block the movement of the detached yarn end to the winder for the yarn to be held while the detaching air jets are active. The blades rotate to turn in opposite directions at the same time round their axes. The blades have alternating recesses so that they can lock together when in the closed setting. ADVANTAGE - The system gives a smooth transfer of the detached yarn end to the winding station.
